WhatsApp's video call bug fixed after critical loophole was exposed

WhatsApp Fixes Bug That Could Let Hackers Crash App During Calls The bug affected Whats App for Android and iOS but the company has now fixed the issue

WhatsApp has disclosed and fixed a massive security flaw in the messaging platform. She found a severe vulnerability in WhatsApp Messenger that could have given hackers complete remote control of your WhatsApp just by video calling you over the messaging app.

If the user takes a WhatsApp video call from a stranger or from a known person, but with ill intention, the latter could take over the victim's phone account and syphon off the sensitive contents.

Natalie in a bug report notes that the "heap corruption can occur when the WhatsApp mobile application receives a malformed RTP packet". The malformed packet that triggers the crash could be sent through a call request.

The bug report explains that the bug affected the iOS and Android users only because they use Real-time Transport Protocol (RTP) for video calls. It does, however, suggest that users will want to be extra-vigilant, both in locking down their account info and refusing to accept calls from strangers. WhatsApp's web client is not impacted because it uses WebRTC for video calls. It is unclear whether the bug was ever used in an attack before it was fixed. We routinely engage with security researchers from around the world to ensure WhatsApp remains safe and reliable.

"Rumours about Facebook fuelling ads on Whatsapp started popping up at the end of last month, stating that ads are coming to WhatsApp for iOS, and now same happens for Android, Android Headlines reported".

The issue also drew the attention of another Google researcher Tavis Ormandy, who in a tweet, said, "This is a big deal".

This exploit was fixed on September 28 for the Android users and on October 3 for the iPhone users via an update.
